Description
Technical field
The utility model belongs to mechanical equipment technical field, and in particular to a kind of bearing support.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment.The linear motion bearing form of early stage is exactly in a row
Row's rod is placed under skid plate.Modern linear motion bearing uses same operation principle, is only replaced sometimes with ball
Roller.Simplest swivel bearing is axle sleeve bearing, it is a bushing being clipped between wheel and wheel shaft.It is this design with
After be scrolled bearing replacement, exactly substitute original bushing with many cylindrical rollers, each rolling element is independent just as one
Wheel.The major function of bearing is the mechanical rotary body of support, reduces the friction coefficient in its motion process, and ensure its revolution
Precision.Bearing can be divided into sliding bearing and rolling bearing according to frictional property, and wherein angular contact ball bearing belongs to rolling bearing
It is a kind of.
The steel ball of angular contact ball bearing and the line and radial direction of Internal and external cycle contact point are at an angle, and contact angle is generally divided into
15 °, 30 °, 40 °, angular contact ball bearing can bear radial load and axial load simultaneously, can work at higher rotational speeds.It connects
Feeler is bigger, and axial carrying capacity is higher, usually takes 15 ° of contact angles with high-speed bearing in high precision, under responsive to axial force, contact
Angle will increase.Single-row angular contact ball bearing can only bear the axial load in a direction, when bearing radial load, will cause attached
Add axial force, and axis or shell axial displacement in one direction can only be limited.If pairs of duplex installation, makes a pair of bearings
Outer ring it is opposite, i.e., wide end surface is to wide end surface, and narrow end surface is to narrow end surface.It can avoid causing additional axial force, Er Qieke in this way
Axis or shell is set to be limited within the scope of end-play in both direction.In common mechanical, rotating speed mainly goes to hundreds of thousands of
Rpm, with the fast development of Numeric Control Technology, " compound, high speed, intelligence, precision, environmental protection " has become current machine tool industry
The main trend of technology development.

It advanced optimizes, the both sides of the partition board are symmetrically arranged with multiple spacer blocks.
It advanced optimizes, the outer ring inner edge is provided with sliding slot corresponding with partition board.
The beneficial effects of the utility model are：
One, the bottom plate setting of support forms certain gap on bear inner ring grooved railway, between bottom plate and bear inner ring grooved railway, should
Extruding of the external force to steel ball can be effectively relieved in structure, reduce the wear rate of steel ball, prolong the service life；
Two, biserial contact ball bearing can bear the radial load of bigger and act on the axial load of both direction, it
Axis or shell bi-directional axial displacement can be limited, Bearing configuration with a higher rigidity can be provided, and tilting moment can be born；
In conclusion support is arranged on bear inner ring grooved railway the utility model, by between bottom plate and bear inner ring grooved railway
Gap can effectively buffer the impulse force that external force generates roller, it is big that biserial roller can bear tilting moment, even if increasing in high speed
It, also can held stationary operation in the case of length.
